Full Description

The influence of bromide ion on the formation of nonpurgeable organic bromine and nonpurgeable organic chlorine was not studied previously because no analytical technique existed that could separately measure total organic chlorine and total organic bromine. This measurement has been made possible with the application of the neutron activation analysis. Thus, this study determined the influence of bromide ion concentrations on the relative amounts of nonpurgeable organic chlorine and bromine and chlorine-substituted and brominesubstituted trihalomethanes formed during the free chlorination of drinking water over various reaction times and pH values. Measurements of this type are important because bromide ion concentrations are not lowered by conventional drinking water treatment processes, bromide ion is present in many groundwaters, bromide ion may increase the production of trihalomethanes, and the health effects of brominesubstituted compounds may be different from those of their chlorinesubstituted counterparts. Includes 9 references, figures.
